Two formula one racing cars are negotiating a circular turn, and they have the same centripetal acceleration. however, the path of car a has a radius of 49.6 m, while that of car b is 39.3 m. determine the ratio of the angular speed of car a to the angular speed of car b.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

Aspecimen of oil having an initial volume of 580cm^3 is subjected to a pressure increase of 4.0 mpa, and the volume is found to decrease by 0.40 cm^3. (a) what is the bulk modulus of the material? (b) what is the compressibility of the material?

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity
